Hey guys just started my journey on tuning. Im looking to maybe find a Ko4 Tune ecu file for a VW Gold MK5 GTI, I have done all the required steps to complete the full ko4 build. Ive created my own tuning map, so far its not bad but i have not dyno to see the outcome of my custom tune. If anyone wants to share stuff on their ko4 gti mk5 build let me know thanks
